Unformatted text preview: 1. Consider the trisubstituted cyclohexane molecule below. Draw the two possible chair conformations for this molecule. Which conformation will be more stable? Explain you answer. 2. Studies of 1,2-ethanediol (HOCH 2 CH 2 OH) show that the conformer in which the hydroxyl groups are gauche to each other is more stable than the conformer in which the Cl hydroxyl groups are anti to each other. However, for 1,2-dimethoxyethane (CH 3 OCH 2 CH 2 OCH 3 ), the anti conformation is favoured. a) Draw Newman projections for the gauche and anti conformers of 1,2-ethanediol and of 1,2-dimethoxyethane. b) Why is the gauche form of 1,2-ethanediol more stable than the anti form? Draw a picture of the stabilizing factor....
